How did John F. Kennedy implement his belief that the Cold War was a test of America’s toughness and strength?

John F. Kennedy, who served as the 35th president of the United States (1961–63), believed strength and toughness were needed to win the Cold War. Although his presidency was brief, JFK faced numerous foreign policy challenges.
The first foreign crisis he faced was the Bay of Pigs fiasco in April 1961. The CIA trained Cuban exiles and landed them in Cuba to overthrow Fidel Castro. It was an embarrassing failure for the United States. Although Kennedy had not planned the invasion, he did approve it.
Kennedy's determination to fight Communism was evident. In 1963, he gave his "Ich bin ein Berliner" speech in West Berlin. In this famous speech, he pledged his support for the beleaguered people of West Berlin. He also sent advisers to Vietnam and deepened America's involvement in that nation.
Kennedy also created the Peace Corps to assist poorer nations throughout the world. It remains as one of his most important legacies.
The most dangerous event of his presidency was the Cuban Missile Crisis (1962–63). Satellite photos revealed that the Soviet Union had placed missiles in Cuba. Kennedy demanded that Moscow remove the missiles, and the world came closer than ever to a nuclear war. Moscow finally agreed, and war was averted.
